Let’s take a closer look at this highly functional product with the models MT-7617 and MT-7618. The features of this device revolve around its detector type, which is InGaAs. The excellent wavelength range it offers spans from 700 to 1700nm, making this tool highly versatile.
It comes equipped with a 2.5mm universal optical connector and has measuring wavelengths of 850 / 980 / 1300 / 1310 / 1490 / 1550 / 1625 / 1650nm. The meter offers a dynamic measuring range from -70 to +10dB, further boosting the appeal of the product.
The high resolution of 0.01dB ensures precise measurements. Accuracy is another strong point; at 1550, 1310nm, it’s ±0.2dB, while at 1490nm, 1625nm, 1650nm, it’s ±0.3dB. At 850nm, 980nm, and 1300nm, you can expect accuracy within +0.4dB.
The power display units are calibrated in dB, dBm, mW, uW, nW, and the device is capable of picking up modulation detection at 270/1k/2kHz.
One of the highlights is its data storage capability, which can house up to 500 wavelengths. This feature complements the wavelength identity functionality and self-calibration mechanism. Moreover, it can use reference values and features a highly visible display thanks to the backlight.
Please note that while it comes with a VFL connector, the VFL output power, test distance, and wavelength are not included in the device. The assistive light of the power meter is LED, and it has a convenient feature which turns off the device automatically after 10 minutes of inactivity.
A handy low battery indication feature is provided along with a micro USB charging port. You’ll be impressed with its AAA battery-powered performance; it can deliver more than 100 hours of functioning.
Lightweight and compact, the meter has dimensions of 98 x 59 x 27 mm and weighs just 70g (battery excluded). It’s designed to function efficiently in a temperature range of -10 to 50℃.
The accuracy and testing length of this device might slightly vary based on environmental conditions, and please remember that batteries are not included in the package.
In terms of what’s included in the package, you will receive 1 Power Meter, 1 USB cable, and a box for safe and easy storage.
Now, let’s go over the visuals. Below are detailed images of the product, displaying its features and design from multiple perspectives.
